IPC: G01P15/11
Filed: 1989-05-12
Abstract: PURPOSE:To detect an unclear fault state by providing a second coil wound round on a circular core adjacently to a first coil and a test signal transmitting circuit connected to an input part of a second coil. CONSTITUTION:For instance, in the case of detecting a fault of an acceleration sensor 1, first of all, a test signal is inputted to an input part of a second coil 6 from a test signal transmitting circuit 19. This test signal is a sine wave or a pulse wave. Subsequently, the test signal inputted to the coil 6 is transferred to a first coil 5 by a mutual induction. Also, when the test signal is inputted, the coil 6 receives force by an action of a ferromagnetic field formed by a magnet 2 and a pendulum 7 is displaced. When the test signal is inputted to the coil 6, if the coil 5 and the displaced state of the pendulum 7 are all normal, a signal corresponding to the test signal is all outputted from the coil 5. That is, by comparing the circuit 19 and the signal of each output part of the coil 5 with the circuit 19, a fault of the sensor 1 can be detected.

NH3 and an organic substance, such as amines, are preferred as the abovementioned basic catalyst. Spherical silica particles, formed by the hydrolysis and having 0.03 to 5mum particle diameter are then naturally settled, filtered or centrifuged and separated from a liquid to afford a silica cake, which is then sufficiently dried, then heat-treated up to 1150 to 1500 deg.C in an He atmosphere or under reduced pressure and transparentized. Thereby, the objective platy silica glass is obtained.

Abstract: PURPOSE:To prevent normal data by appearance from being outputted as a transmission signal by monitoring the cycle of a reception signal frame timing pulse and fixing the transmission signal at '0' or '1' when abnormality is generated in the cycle. CONSTITUTION:By taking the AND of a reception signal frame timing pulse RDF and the overflow pulse of a write address counter circuit 2 by an AND circuit 4 and monitoring the cycle of the output pulse by a monostable multivibrator circuit 5, it can be decided whether the cycle of the reception signal frame timing pulse RDF is normal or abnormal. Therefore, it is possible to fix the transmission signal TD at '0' by taking the AND of the output signal of the monostable multivibrator circuit 5 and a readout signal from a memory circuit 1 when the cycle of the reception signal frame timing pulse RDF is abnormal. Also, it is practicable to fix the transmission signal TD at '1'.

The deviation of the density of color based on the error of the sensitivity of the film and the error in the development processing or the deviation of the tone of color due to the external light condition is detected, and a color tone adjusting part 23 and a color density adjusting part 34 control the filter and the exposure time of an exposure part 26 for the purpose of correcting this deviation. Thus, the tone and the density of color which the person feels at the time of photographing are recorded and reproduced.
